Description
| - Testovali jsme hypotézu, že při sukcesi v opuštěných čedičových lomech je složení vegetace ovlivněno vzdáleností a rozlohou ochranářsky významných stanovišť stepních trávníků. Ve 34 lomech v Českém Středohoří bylo pořízeno 270 vegetačních snímků. Ordinační a regresní analýza založená na fidelitě snímků ke společenstvům Festucion valesiacae a Allyso-Festucion pallentis ukázala, že pravděpodobnost vývoje těchto společenstvev klesá se vzdáleností k takovým společenstvům v okolí. Pravděpodobnost rozvoje těchto společenstev též stoupá s dobou od opuštění lomu, tento vztah však je potlačen, je-li identita lomu použita jako kovariáta. Nacházejí-li se do 100 m od lomu cenné stepní trávníky, jejich druhy jednou kolonizují vytěžené plochy. Těžaři by měli už během těžby pečovat o cenná stanoviště v okolí lomových jam, protože přítomnost ochranářsky cenné vegetace v okolí v budoucnu sníží náklady za rekultivační či revitalizační práce.

- We tested the hypothesis that the composition of vegetation formed during primary succession in quarries is affected by the distance to, and area of, valuable biotopes the quarries. The successional vegetation was recorded in 34 quarries in the area of Ceske Stredohori Hills, Czech Republic. Regression analyses of fidelities of individual releves to the grassland alliances Festucion valesiacae and Allyso-Festucion pallentis corroborated the view that the probability of development of valuable habitats within the quarries decreased with distance to the closest grassland sites, and increased with their area. It also increased with successional age, but this effect was suppressed if quarry identity was considered as covariable in the regressions. The valuable biotopes would eventually develop in quarries situated less than 100 m from adjoining xerophilous grasslands.
